3 Claims. (Cl. 164-48) This invention relates to fish hook making and,more particularly, to a method of and mechanism for pointing sh hookblanks. The invention is illustrated as embodied in an automatic iishhook making machine of the type disclosed in United States LettersPatent No. 2,379,886, granted July 10, 1945, upon application filed inthe names of W. J. De Witt et al.

In pointing blanks, such as fish hook blanks, by means of automaticmachines, considerable difculty has heretofore been experienced inproducing uniform blanks With smooth, Well-.centered points.Accordingly, it is an object of the present invention to provideimproved mechanism for forming pointed blanks which will be particularlyeffectivev in its operation in that it will rapidly point blanks with aminimum of crippled blanks and Vprovide a product which is uniform inshape.

To this end, and as herein illustrated, We have provided mechanism, in amachine of the type referred to, including means for feeding Wire apredeterminedv distance past an operating station, thus to control thelength of the blank to be produced, and mechanism for shearing the Wireat the operating station simultaneously in two places, at right anglesto and at an acute angle to the axis of the Wire, thus toproduce a blankhaving a partially formed pointed end and, at the same time, to form thebutt end of a succeeding blank. Preferably, and as shown, the Wire, whenit is fed, is received in a chuck carried by a turret, there beingmechanism operable after the severance of a blank, to move the blank toswaging mechanism. The swaging mecha.- nism, as illustrated, comprises arotary die arranged to be moved axially of the blank to engage thepartially formed pointed end of the blank to sWage it, thereby tocomplete the point.

In another aspect, the invention relates to a method of making fishhooks in which Wire is intermittently fed past an operating station andblanks are successively severed from the wire by shearing the wire atthe operating station along planes at right angles to and at an acuteangle to the axis of the wire, thus producing blanks each having apointed end portion and a formed butt portion.

These and other` features of the invention are disclosed in thefollowing specification and in the accompanying drawings, and are setforth in the claims.

In the drawings:

Fig. 2 is a view in side elevation of the mechanism shown in Fig. 1;

Fig. 3 is a cross-sectional View taken along line III- III of Fig..2 andshowing details of the shear mechanism;

Fig. 4 is a view in front elevation of the angle shear and cut-offmechanism;

Fig. 8 is a side View of a fish hook blank after the vbutt end and thepointed end have been formed by shearing operations; and

Fig. 9 is a side view of a blank With a complete point.

The mechanism herein shown operates to sever blanks, such as blanks I0(Fig. 8), from a length of wire l2 (Fig. 1), forming a butt end portionI4 and a pointed portion I6 (Fig. 8) by a shearing operation, and toform a completed point I8 (Fig. 9) by sWaging the partially formed pointI6.

The shearing mechanism comprises fixed shears in the form of blocks 20and 36, best shown in Fig. 3, rigidly mounted upon the frame 22 of themachine, and a movable shear 24 mounted for movement heightwise of thefixed shears, the cooperating shear members being arranged to extendupon opposite sides of the line of feed of the Wire I2 to be formed intoblanks. The xed shear 20 has an operating face 26 located in a verticalplane extending across the line of feed at an angle of about 30, theface being slotted, as indicated by reference character 28, to provide apassage through which Wire can be fed. The movable shear has a face 3f)also extending vertically and in alinement with the face 26 of the xedshear, and also has a second face 32 located in a vertical planeextending normal to and across the axis of feed. The face 32 is arrangedto cooperate With a vertical face 34 of the shear block 36 to form thebutt end of a blank.

IThe wire l2 is arranged to be advanced across an anvil 38 and through aguide opening 40 in the shear block 36 and through the elongated slot 28of thexed shear 20.

The means for feeding the wire comprises a pair of grippingjaws 42 and44 (Fig. 1). 'Ihe jaw i2 is iixedly secured to a slide block 46, and thejaw 44 is mounted upon a lever 48 pivoted on a stud 59 secured to theblock 46. The lever is reciprocated by means of a rod 52 under controlof a cam (not shown). Rearward movement of 3 the lever relatively to theblock is limited by a stop screw 54. The slide block 46 is arranged toreciprocate along a guide member 56 upon actuation of the rod 52. Duringthe rearward movement of the lever and slide the jaw 44 is moved aboutits pvotaway .from the jaw 42,.,so that no f orceisfexertedrupon theywire (i2. i1-Iowever, upon forward movement of the lever `52 and block46, the jaws are forced together, gripping the wire and advancing itoutwardly past the shear members. The length of the blankgtprbe producedis determined by the `distance which the wire is advanced past itheshearmembers, and this in turn is determinegdgbytheamount;of forward movementof the actuating rod .5 2. )In order to hold the blanks as they are cut01T from the wire there is provided arturreti'carnying a plurality ofchucks 62, each of which is Igarranged to receive wirecas it is advancedby the wire feed ,mechanism. I o this end, each of ,the chuckscomprises-a stationaryjjaw B4 and, a-rnov able jaw 66 c arried at thenpper end-'oiga spindle J63 extending jdownwajrdlyg'throughA the bodyllortion ofthe chuck. *Themovable jawis normally forced downwardly bymeans of a 'spring `Hl -surroun'dingthe` plunger vand^bearing against'the lower surface ofthe ;chuck and a washer 12 Yupon the lowerfend ofthe plunger. f The topening'and -closing -of the Yjaws-is controlled bya trip rod ,14 actuatedby a cam 76.

The ,amount of V pressure of theleverruponthejplunger can'be'varied by means A of a -setscrew `913.

The `movable shear is 4operated"by means of a `vertically extendingplunger '95 h(Figs.

llt `is to lbe -noted that the distance tbetween the lfaces-S361! -and32 ofthe YAmovable shear, Where those lfaces A'cross the vpath-offeed-of-the-Wire 12, is comparatively small, with the result that 'whenthe movable shear descends the piece of wire cut out of the main lengthof wire is comparatively small. Thus there is little waste of materialinvolved in severing the wire. Operation of the shears results insimultaneously partially .forming the p oint of one blank .andiormingthe 'fbutt end .tof ithe next succeeding iblar'rk. This serves tominimize the number of operations necessary in producing pointed blanks.

After the shearing operation the turret is rortateiito position a chuck62, with a partially hointedlalank therein, in operative positionrelatively tothe swaging'mechanism shown in Fig. 6. .'Ihe -mechanism formoving the turret is not '.helin-5hown in detail, but is preferablysimilar to that disclosed in the aforementioned United States laettersPatent.
